用心阻抗微分图检测动脉导管未闭(PD)的临床价值,国内报道不多。本文对6例 PDA 患儿与健康儿童,以及动脉导管结扎术前后心输出量和心收缩间期的动态变化进行了研究并探讨其机理。笔者采用心阻抗微分图、心音图,心电图等同步记录,进行了观察,现将结果报告如下:
The differential diagnosis of cardiac impedance patent ductus arteriosus (PD) clinical value, few domestic reports. In this paper, 6 cases of PDA children and healthy children, and before and after catheterization of cardiac output and cardiac contractility dynamic changes were studied and discussed the mechanism. The author uses the heart impedance differential diagram, phonocardiogram, ECG and other simultaneous records, were observed, the results are reported as follows:
